Terrified of having a second baby

Celi
I have a 10 month old son and my husband and I talked about having 3 kids. We want to have them sooner rather than later but now that I've experienced all that is baby I am so terrified to add another while having a toddler. I want more kids and I don't want to wait too long. I'm not pregnant yet but I definitely keep postponing trying for another. I just don't handle well too much at once going on. Anyone got an encouraging story to share to help me out?
